He has the site at http://www.avdb.com, and anybody can add their info to it. If you have a finished and flying KR and are interested, go there and post your stats. So far no KRs on it; he's just starting out. I guess Tom Crawford can list his KR's airspeed numbers in Mach, since his bird has a Machmeter ;o) Oscar Zuniga Medford, Oregon website at http://www.geocities.com/Pipeline/Dropzone/5610/ _______________________________________________________________ Get Free Email and Do More On The Web.

Any suggestions on a substitute. Maybe some quick cure from a local hobby store or some spray adhesive from 3M. Next Question, The fiberglass that Wicks sales, KR glass (KR7533), is listed as plain weave, but in the beginning of the KR Manual it says to use all BID cloth. Any thoughts on that one? Next Question, Did you Fellows use the Finnish grade plywood or the Mil spec plywood. I am leaning towards the Mil spec due to getting the Sheets in 4x8 size. (less scarfing) I know that the Mil spec is suspose to be better grade stuff, but Wicks lists using the Finnish grade in the section where they divide up the KR-Kit. Thanks for your help.

Had to demonstrate performance to the FAA, and certify intensity and coverage. This time, I'm buying commercial. The power input is a good quality indicator.... If it only draws 200 Ma, it only puts out that much light. It won't be useful in daytime nor approved for night. One of the most effective collision avoidance tricks is to run with your landing light on....... It's very easy to see, even coming out of the sun. Our GM aircraft turn them on whenever they go below 10,000 feet. ---------------------------------------------------------------------- Subject: Re: glue, wood and fiberglass From: "Richard Parker" Date: Thu, 29 Apr 1999 10:18:46 PDT X-Message-Number: 7 The 4 minute epoxy is made by Devcon and can be found at most hardware stores and your local ***Mart in double syringe tubes.

As I was unloading the fuselage and the rest of the wood into my garage I noticed another set of center section spar material. Now why would there be spars in the boat plus extra spar material? I stopped the unloading and inspected the spars, on the extra wood, (dimensioned to make center section spars) was a pitch pocket about 2 1/2" long and 1/8" wide. Now I haven't talked to the man I bought the project from, but by the invoices I got with the boat it was all purchased from AS&S. He either purchased new spar material, which he used to build the spars, or AS&S replaced them when he reported the pitch pocket. Now the moral of this story is always check the material you receive from any supplier no matter what their reputation might be, anyone can make a mistake and it's your butt on the line. You know if I cut it at a 45, varnish the wood I could have a nice set of 2" wheel chocks. Hmmmmmmm! Dave Moore David G.

He has gone to considerable effort to find me a Corvair engine there and prepare some parts that I can't have machined here where I live. Corvair engines were not available in my area.(after a 6 month search). So I was surprised to hear of Mr. Wynne not filling your order - very surprised. It is like hearing about a completely different person than the one I dealt with. If I know Mr. Wynne, I'd bet he has tried to contact you already and contact was missed. Perhaps he is not getting your messages. Maybe he didnot recieve your order. He does have to travel a lot - like many of us do. And he was very busy during the month of March and April getting ready for Sun N Fun. His Corvair plans are real good. I am glad I have them. Tom Cummings -- >> I do not know what the problem is.

Out of the 5 calls placed to him, 4 times an answering machine was gotten, the fifth time my lady friend called him and was told that they would be sent within a week. That was about the 20th of March, this is now the 29th of April. That is more than 1 week the way that I count time. As for his plans being very good I'm sure that they are, if you can get them. I have heard from more than one source that they are good plans. I have had no calls from him at all. He may not have my number, as you seem to have a good relationship with him, my number is (818)704-6168. If it would get the plans too me a collect call would be very acceptable.

"Typical" doctors bust their butts 10-12 hours a day seeing patients, and then end up getting summoned to the hospital to take care of the little old lady that crashed her car into a curb and cracked her pelvis. "Typical" doctors give up prestigious positions as directors of pathology and move to small towns to practice because they feel there's a need. "Typical" doctors, after retirement, get together and form health clinics for the less fortunate, donating their time and expertise rather than spending the day on the golf course with the other retirees. "Typical" doctors, after medical school, return to the rural office or clinic where their father has practiced to carry on the family tradition of serving the community, rather than accepting positions in the proverbial Big City. "Typical" doctors travel to third-world nations, without compensation, to provide services to people who would otherwise have no chance of receiving even basic medical care. These are just a few of the "typical" doctors I've come across. >> That is the typical Doctor that I know also. I have often wondered how Dr Dean manages to have time to devote to the KR. But then the typical Dr that I know is a workaholic so that explains a lot too me, right there. Most of them end up getting divorced several times in their lives because of it. I'm not a Dr but my scedule is similar and it takes a toll on a relationship. Ok, I'll get off of the soap box and give room to someone else.

It seems that Ken did this very thing at Osh one year. The article showed him repairing the damage. Looks to me like all he did was glue in some more foam, sand it to the right contour, apply a layer or two od dynel fabric and he was done.

Any thoughts on that one? There are a lot of weaves that are bi-directional (BID). The simplest ones are the plain weave.

Anyway this past weekend he got her fired up and it sounded pretty beefy! Max static RPM with the 1835 was about 2850 or so with a 52x48 Props Inc prop. Max static RPM with the 2300cc is somewhere over 3300rpm! The reason I say somewhere is its not quite running right yet and I feel there is more RPM in there somewhere. We had one unexplained phenomena occur. We could run the RPM up to 2900 or so and everything sounded great but anything beyond that RPM and the engine started letting out a BIG bogging noise. If any of you are familiar with 2 strokes it sounded like a two cylinder 2 stroke running wide open on one cylinder. It was incredibly loud and had a very "harmonic" ring to it. We first thought the Ellison wasn't supplying enough fuel and this was the source of the noise but after playing with the carb heat box a little we decided the noise was NOT coming from the carb. After a while Allan gave up for the day and while he was pushing the airplane back into the hanger he noticed on the backside of one blade of his prop the finish coat was cracked very badly. The cracks were chord wise on the prop and only on one blade. We started thinking that maybe the noise was the prop doing something weird at any RPM above 3000. Anyway Allan was heading over to borrow a Sterba prop to see if the noise was in fact coming from the prop. I will keep yall posted on what we find. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Ailerons almost done! http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo CA Give Blood, Play Hockey! ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: VW engine upgrade report From: BSHADR@aol.com Date: Fri, 30 Apr 1999 02:26:14 EDT X-Message-Number: 18 In a message dated 4/29/99 8:03:38 PM Pacific Daylight Time, mikemims@home.com writes: << After a while Allan gave up for the day and while he was pushing the airplane back into the hanger he noticed on the backside of one blade of his prop the finish coat was cracked very badly.
